Unformatted text preview: = 5.28 V 9. ? . Thus, An engineer measures finds that with an input voltage , the output voltage is , so that the gain of the amplifier is 6. However, op-amp theory suggests the ⁄ gain is . Give one phrase that could explain the difference. Slew-rate 10. The output voltage of a three-terminal voltage regulator is 5 V @ 5 mA load, and 4.96 V @ 1.5 A load. What is the regulator’s output resistance? Answer. ⁄ ⁄ 2 55:041 Electronic Circuits. The University of Iowa. Fall 2011. 11. Below are the characteristics for a MOSFET. What type of FET is this (circle one)? (a) Enhancement PMOS (b) Enhancement NMOS (c) Depletion NMOS Answer: Depletion NMOS => (b) 12. Below as possible ordering for (a) (b) (c) (d) ( ( ( ( ( for several LEDs. Circle the correct one. ( ( ( ( ( ( ( ( ( ( ( Answer: (a) 13. True or false: in MOSFETs the drain current is directly proportional to the width-to-length ratio. Answer: True 14. Briefly explain (1–2 sentences) what is ( as it pertains to MOSFETs. (2 points) This is the lower channel resistance that one can achieve when turning on a MOSFET. That’s is, the resistance between drain and source when (for an NMOSFET). 3 55:041 Electronic Circuits. The University of Iowa. Fall 2011. 15. True or false: given the symmetrical construction of MOSFETs one can, in principle, at least, interchange the drain and the source terminals without affecting device behavior. Answer: True 16.
